Koyo N-FLO Dual Pass Radiator for 1989-1994 Nissan 180SX/Silvia S13 SR20DET (MT)

The Koyo N-FLO Dual Pass Radiator is a high-performance all-aluminum cooling solution designed specifically for manual transmission Nissan 180SX and Silvia S13 models equipped with the SR20DET engine from 1989 to 1994. Featuring Koyorad's advanced N-FLO Technology, this radiator incorporates internal aluminum partitions that create a dual or triple pass coolant flow, significantly improving heat dissipation by increasing coolant retention time within the radiator.

Constructed with a 48mm thick core and ultra-high fin density, the radiator maximizes heat transfer efficiency while maintaining a direct factory fit for easy installation without engine modifications. The radiator retains stock fan mounts and is Nocolok brazed for superior durability and corrosion resistance.
